Database Administration Survey

Jul 23, 2005

Hi,

We are a systems research group at the Computer Science department
at
Rutgers University, and are conducting a survey to understand details
about network, systems and database administration. We hope that this
information would help us recreate a realistic environment to help
research in 'systems management'.

We request network, systems, and database administrators to take this
survey. As an incentive, all surveys completed in their entirety will
be
entered into a drawing of a number of $50 gift certificates (from
Amazon.com).

We hope you have a few minutes to take the survey which is located at:

http://vivo.cs.rutgers.edu/administration_survey.html

Research in our group:
The goal of our research is to improve the overall availability and
maintainability of services. Since administrators form an integral part
of these services, a key aspect of this work is to build environments
and tools that ease the task of service administration. In particular,
environments which would help administrators know how their actions
might impact the real service (before performing them for real), we
believe would be useful in preventing inadvertent actions. This survey
tries to understand the existing environments, what administrators do
currently to test the 'validity' of their actions, and the difficulties
they face in doing so. The two specific systems we are looking at are
networks and databases, as we believe these are important components of
many services.

If you have any questions regarding this survey or our work, feel free
to email us:
Fabio Oliveira (fabiool at cs || rutgers || edu), or
Kiran Nagaraja (knagaraj at cs || rutgers || edu)

Thanks for your time,

Fabio Oliveira

Web Survey Database Design

Aug 26, 2005

I am a developer and I have a problem trying to design a system tomanage data coming from web surveys. Each section can potentially havedozens of questions, i.e., fields.I am focusing here only on the table(s) that will hold the survey data.I do not have any DDL as I am still trying to understand this!All the examples I have found so far in books and on the web seem todeal with fairly limited data, that is easily, or so it looks, brokendown in multiple tables.It seems that, from my research, having a wide table per survey sectionwith each field as a column, which has been suggested to me, is notproper design for many reasons - missing values for non-requiredquestions, table with 100s of possible columns, etc... - so I playedwith the idea of a single table where one of the columns would be theforeign key pointing to a questions table and another column would holdthe data (this is a simplified explanation.)The problem with this is that now this column will have to accomodateall types of data, from bits to large varchars, and that fieldvalidation seems now impossible jeopardizing data integrity.What do knowledgeable designers come up with in this case? Can someonepoint me in the right direction?Jerry

Database Administration

Oct 5, 2001

To All SQL Guru's

I have this simple problem. How can I make SQL Enterprise Manager list only one database that is accessible by client who registered the SQL Server on his / her Enterprise Manager. The user has been granted access to only one database. But every time I register the server in the client's SQL Server Enterpise Manager it lists all database and user database with it.

I just want it to show only one or two or as how many database that login has granted access to and eliminate the database from the SQL Server Enterprise Manager's database list.

Please Help

Thanks

SQL Database Administration Tool

Jun 26, 2005

Hi...
Does anybody know of an open source script I can download that will enable me to manage an SQL database? I basically need to access and modify the database from any machine that may not have SQL Enterprise Manager Installed. I was thinking of writing my own script to do this but I assumed that there is probably already one out there.

Sql Server Database Administration Web Application

Sep 10, 2006

Hi All, I will shortly (hopefully) begin devleoping an ASP.Net web application to let users manage a remote sql server 2005 database (kind of like the php myAdmin tool for MySQL databases). Were not talking a server managament tool for DBAs, more an end user tool for managing personal databases (it seems that web hosting companies provide tools for MySQL, but if you use SQL Server, you're stuck unless you have management tools on your PC - and what about mac users?).Given that premise, what features should i attempt to include? Creating and modifying tables structures and data is an obvious inclusion, but what else? I also haven't yet decided whether to go about this using scripts or using SMO. I've read that SMO is backwards compatible across versions of SQL Server...how true is this? are there issues or is it seamless? Please post any comments or thoughts you have, and thanks for taking the time.

Database Administration/Maintenance - Guidance Needed

May 16, 2006

I have been working SQL server for many years as a web developer, however in my current position we are lacking an expert in maintenance and admninistration as the company has recently switched over to SQL Server 2005.

I therefore need to develop a greater understanding of the best practices with regards to administration and am a bit lost as there are so many options which seem like they might match my requirements. As I have never looked beyond the basic administration/maintenance side of things before I have no idea which options to investigate.

Basically I want to clear any records older than 3 months old on a scheduled/automatic basis. There seem to be various options that could do this, however I want to know what the best option is, rather than waste a lot of time and risk problems by resorting to trial and error.

We are already backing up this data, however I am not sure if I should combine these tasks. It is highly unlikely that we will ever have to restore these older records, however we do need to store the data for legal reasons.

I dont expect anyone to tell me everything, as I am happy to investigate, I just need a nudge in the right direction.

Thanks

Survey DB Schema

Dec 12, 2004

I am trying to modify a survey DB schema created by OOP(Object Oriented Programming) snobs who had their heads so far up their butts(in my opinion).
This is current schema created by them.

Diagram 1 (OOP snobs version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/2761.jpg?phsEJvBB3t1v7URD

Actually there aren't a several foreign keys as they are shown in the picture, but that's what they(OOP snobs) are doing to the table "Response". They are inserting question_collection_id and its name as well as question_id and its name to Response table. However, it was not ill-intended, "We just wanted to load the report quickly"(OOP snobs).
But I really recommend this schema, Because of its simplicity.

Diagram 2 (My version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/e890.jpg?phrEJvBBF0.lGY5Y

Yet I haven't proven that my schema will provide report just as quickly as OOP snobs' version. As mentioned earlier, since they don't have foreign key constraints accordingly, I do find quite number of discrepancy on values of "question" columns between "Question" and "Response" tables and "question_collection" columns between "question_collection" and "Response" table. I can provide schedule task to eliminate those problems. But I really prefer my schema than theirs. So far, I can explain mine is better just because of its simplicity and DBA's gut instinct. I'd like to hear Superior Expert's opinion which schema is better and why one is better than the other.

Attached is also zip files of schema images if you can't see them by those URL.

Would You Like To Participate In The BI Survey?

Jun 16, 2007

The BI Survey is the largest independent survey of BI technology users worldwide. (It used to be known as the OLAP survey, but has expanded to cover a broader array of BI technologies.) The survey analyzes people's buying decisions, BI implementation cycles and business results achieved.



The BI Survey is strictly independent --- they ask vendors like us to ask our customers like you to participate, but we don't have any other involvement --- except closely reading the results, of course. The Survey will send all participants a summary of the full survey results and place them in a drawing for ten $50 Amazon vouchers.



You can complete the survey on-line by following these links:

SQL Server DBA Salary Survey

Aug 29, 2006

I am going into salary negotiationyearly review next month after my week off and I am trying to determine what to ask for. I am thinking another 10K and an extra week off would not be unreasonable, but I wanted to get some idea of what you guys think I should ask for in terms of pay.I have been developing software for seven years and I have been a dba for a little over five. I live in pricey northern Virginia. On a fairly regular basis I do about 55 to 60 hour weeks. On my DBA team, I am the only one who can handle both development and production tasks. The others are strictly developers. Although I have been relieved of most of my customer support tasks by our newbie, the customer support manager still brings the nastier bits to me. It is my perception that the more complex tasks get assigned to me. I get told on a regular basis that I am the best dba this place has ever had and other embarrassing accolades are regularly thrown my way. After a year, other than my boss I am the dba that has been here the longest in high turnover high burnout company. This year as we try to move to a SAP model, it looks like we will be going to 24/7 support on a disaster recovery model I am designing and implementing, so I guess I am getting the pager.So how much money should I be asking for?you can PM me with a number if you want.

Calculating Survey Scores

Oct 16, 2007

I have surveys that I need to add weights to and was wondering if there was a way to convert the contents of a column.

select empid, ans_for_ql,
(if ans_for_ql = A then 0, B then 3, C then 5) as weightscore,
ans_for_q2,
(if ans_for_q2 = A then 8, B then 4, C then 2, D then 1, E then 0) as weightscore

Here is what the table looks like:

empid | Ans_for_Q1 | Ans_for_Q2
1001 A C
1002 B E

And these are the possible answers and what they need to be converted to:

Weights for answers to Question1
Q1_A = 0
Q1_B = 3
Q1_C = 5

Weights for answers to Question2
Q2_A = 8
Q2_B = 4
Q2_C = 2
Q2_D = 1
Q2_E = 0

DB Design Question - Survey System

Jul 23, 2005

I've written several survey systems in which the majority of the questionshave the same or similar responses (Yes/No, True/False, scale of 1 - 5,etc).But this latest survey system I'm working on has 8-10 sections, with avariety of question attributes and answer scales. Some items have just adescription and require a Yes/No answer, others have a description and anactive status and require a Yes/No and price answer, some require a comment,etc.Rather than build a separate response table for each survey section, I wasthinking of building one generic response table, and trying to force allsections to fit by adding columns - some of which won't apply to some items.Like this:Survey Category (will apply to all items)Survey Section (will apply to all items)Item Description (will apply to all items)Item YN (will apply to all items)Item Price (will apply to about 10% of the items)Item Points (will apply to about 10% of the items)Item Active YN (will apply to about 10% of the items)Item Fail YN (will apply to about 10% of the items)Item Comment (will apply to about 10% of the items)For instance, in the structure above the field "Item YN" would representmultiple types of answers: is the item in use?, is the item in place?, isthe item given away for free?, is the item on display?, etc. Basically,anywhere a Yes/No answer is used.The advantage is one source table (rather than 8) for storing answers, andit might be easier to query and report on.The disadvantages I see are 1) it's more difficult to understand the meaningof the responses when the answer field is named Item YN, and 2) you have anon-normalized table that's difficult for a 3rd party to understand.If I have the questions and responses in separate tables, I'll use nameslike "ItemComplimentaryYN" and "ItemUsedYN" depending on the question. It'seasier for others to learn the data.I actually don't like the "generic" approach, and probably won't use it, butI figured I'd try to get some input from others who've written surveysystems.Thanks

Using Nvarchar(max) For All Data Types In A Survey System

Apr 23, 2008

I am working on a survey system with another DB Engineer.Our current design includes 1 table per Question Type (Numeric, Boolean, Text), Response values are tightly coupled based on data being entered, to keep things simple assume there are only 6 tables in this this system (1 for each Question Type to define the "rules" of the data entered, and 1 for each Response collection).He is a former .Net programmer and has been talking with the .Net guys on the project and he is proposing that we abstract our Question Types to use one table and store the Input Values all as nvarchar(max).This obviously simplifies the DB design and reduces the amount of work I will need to do so I should be all for it. I guess I am a little concerned that we are no longer tightly coupling the data types and essentially leaving all the validation up to the application. Also should I be worried that a bunch of bit data will be stored as 1/0 in an nvarchar(max) column?Thanks,-John

Design Question For Survey/questionnaire Type Application

Dec 20, 2007

I am a developer and I have a problem trying to design a system to
manage data coming from web surveys. On average each subject will take
part in more than one survey and each survey may potentially have 100+
questions.

I am focusing here only on the table(s) that will hold the survey
data.

I'm thinking about having a wide table storing each question in the
survey(s) as a column against the subjects. My main concerns with this
approach:

- the "yuckiness" and potentially other performance issues(?)
associated with a table with 100s of columns
- the 8kb size limit per row (unlikely to touch it, but possible)
- 1024 column limit (unlikely to touch it, but possible)

Another approach obviously is to have a single table where we have, in
a simplified version, 3 columns: person_id, question_id and data/
answer. The problem with this is that the "data" column will have to
accommodate
all types of data, from bits to varchars, and that field validation
seems now impossible jeopardizing data integrity, and most
importantly, you can't easily work with the data in filtering/
reporting etc.

What do knowledgeable designers come up with in this case? Can someone
point me in the right direction?

Analysis :: Conditional Sum Based On Latest Survey Answer

Jul 24, 2015

Basically our cube contains two different Facts:

- Sales Volume: Information about sold articles to a customer incl. Selling date
- Survey: irregular answered survey questions about customers incl. date of answer
and three Dimensions:
- Customer
- Date
- Survey Answer: Information about possible Answer values (e.g. Yes / No)

Relations:
Fact: Sales Volume  ------>  Dim: Customer  <------  Fact: Survey   ------>  Dim: Survey Answer
                    '-------------->      Dim: Date       <----------------'

We would like to be able to determine the aggregated sales volume (sum) of a customer for a specific period depending on the latest survey answer within this period.

For example:
Selected Time period: Jan - Jul 2015
Sales Volume Customer X - Jan - Jul 2015: 1000 Litres
Sales Volume Customer Y - Jan - Jul 2015: 500 Litres

Surveys answered:

15th Jan 15: Customer X, Survey Question A: Yes
2nd Mar 15: Customer X, Survey Question A: No
20th Apr 15: Customer X, Survey Question A: Yes

10th Feb 15: Customer Y, Survey Question A: Yes
20th Jul 15: Customer Y, Survey Question A: No

Latest survey answer (Jan-Jul) Customer X, Question A: Yes
Latest survey answer (Jan-Jul) Customer Y, Question A: No

Excel Pivot should show something like this:

Question       |      Latest Answer:     Yes                |       No         |

------------------------------------------------------------------------------------
A                    |     1000 Litres     |    500 Litres    |

How this is possible and has to be implemented?

Can You Do SQL Server Administration From An ASP.NET App?

Is it possible to write an ASP.NET app that can do certain SQL Server 2000 administration tasks, specifically add sql server users, and change sql server user passwords?  Would it just be a matter of running the appropriate system stored procedures (sp_password, etc.), or does .NET provide any hooks into SQL Server for something like this?  Thanks!

Remote Administration

Nov 28, 2000

Hi all,
We are about to have 'colocated servers' for our web pages, mail and on line catalogues. The NT administrator is going to use 'pcAnywhere' to administer the servers. I prefer to register the SQL server in Enterprise Manager,using the IP address.

Are there any known advantages between pcAnywhere against using enterprise manager, particularly any security issues?

Many thanks in advance
